Method and system for cardiac imaging and catheter guidance for radio frequency (RF) ablation

Abstract

A method for imaging for cardiac catheter guidance comprises displaying a two-dimensional (2D) image of a heart, including a catheter; registering and blending the 2D image and a three-dimensional (3D) image of the heart to derive a blended image; displaying the blended image and the 3D image; and extracting an image of the catheter and inserting it into the 3D image.

Description

technical field [0001] The present invention relates generally to computerized imaging as can be used to locate specific points in an organ, and more particularly to providing images of the heart and catheters for facilitating placement and manipulation of catheters for the treatment of atrial fibrillation. Background technique [0002] Reference is hereby made to co-pending U.S. Provisional Patent Application No. 60 / 726,597 (Attorney Docket No. 2005P18854US), filed October 14, 2005, and the inventors of which are Rui Liao, Chenyang Xu, Yiyong Sun, and Frank Sauer, and that patent application is titled Method and System for Catheter RF Ablation Using 2D-3D Registration (method and system for catheter radiofrequency ablation using 2D-3D registration), and the disclosure of that patent application is hereby incorporated By way of reference and claiming the benefit of priority from this patent application. [0003] Atrial fibrillation (AFIB) is a major cause of stroke in human...

Problems solved by technology

[0006] The recently released software described in the above reference by Sun, Y. et al. still requires an expensive cardiac mapping system and a dedicated catheter to provide the 3D position of the catheter for 3D / 3D registration and catheter tracking
